Surgical Precision: Weizhong’s 0.01° Radar Testing Platforms

In 2010, Shenyang Weizhong Revolving Machinery Co., Ltd. reached a new pinnacle of mechanical accuracy by delivering two massive rotary platforms—measuring 15 and 18 meters in diameter—for the CETC 54th Research Institute. These systems were specifically engineered for the rigorous demands of military-grade antenna testing and high-frequency radar calibration.

The core challenge of this project was achieving a positional precision of 0.01 degrees. In the world of satellite communications, even the slightest deviation can result in significant data loss. Weizhong’s engineers implemented an advanced stepping motion mode, allowing these gargantuan structures to rotate at precise speeds and stop at predetermined angles with zero-tolerance accuracy. This enables researchers to automate complex test sequences and achieve the repeatable data necessary for high-stakes R&D.

Utilizing our proprietary Pin-Gear drive technology, these platforms provide the high-torque engagement required to stabilize massive antennas against environmental factors during testing. The integration of precision-ground gears and heavy-duty structural bearings ensures that the 18-meter platform remains perfectly level and vibration-free throughout its 360-degree range of motion.

This landmark installation reinforces Weizhong’s status as a trusted partner in national defense and aerospace infrastructure. By merging massive load-bearing capacity with surgical angular precision, we continue to provide the foundational technology that drives advancements in global communication and security systems.
